2.11 System purging

If explosive gases are to be used, purge the process with inert dry gas like Nitrogen, Argon etc. for at least

30 minutes at a high enough flow.

In systems with corrosive or reactive fluids, purging with an inert gas is absolutely necessary, because if the

tubing has been exposed to air, introducing these fluids will tend to clog up or corrode the system due to a

chemical reaction with oxygen or moist air.

Complete purging is also required to remove such fluids from the system before exposing the system to air. It

is preferred not to expose the system to air, when working with these corrosive fluids.

2.12 Seals

Bronkhorst Cori-Tech B.V. has gathered a material compatibility chart from a number of sources believed to

be reliable.

However, it is a general guide only. Operating conditions may substantially change the accuracy of this

guide. Therefore there is no liability for damages accruing from the use of this guide.

The customer’s application will demand its own specific design or test evaluation for optimum reliability.

So check if the seals like O-rings, plunger and packing gland of the capillary are correct for the process.

2.13 Equipment storage

The equipment should be stored in its original packing in a cupboard warehouse or similar. Care should be

taken not to subject the equipment to excessive temperatures or humidity.

2.14 Electromagnetic compatibility

Conditions for compliance with EMC requirements

All instruments described in this manual carry the CE-mark.

Therefore they have to comply with the EMC requirements, as they are valid for these instruments.

However compliance with the EMC requirements is not possible without the use of proper cables and

connector/gland assemblies.

For good results Bronkhorst Cori-Tech B.V. can provide standard cables. Otherwise follow the guidelines as

stated below.
